This study examined whether adolescent students' externalizing behavior and prosocial behavior affects their academic achievement (i.e., school grades and standardized test scores) in two major academic domains (i.e., mathematics and German) over and above well-established determinants of school achievement (i.e., prior achievement, intelligence,…

To promote pro-environmental behavior (PEB), it is crucial to understand the drivers behind it. Studies indicate that, in addition to environmental attitudes and nature activities, interest in nature drives people to engage in PEB. However, the relationship between interest in nature and PEB is still greatly understudied among adolescents even…

We tested whether a brief self-affirmation writing intervention protected against identity-threats (i.e., stereotyping and discrimination) for adolescents' school-related adjustment. The longitudinal study followed 639 adolescents in Germany (65% of immigrant descent, 50% female, M[subscript age] = 12.35 years, SD[subscript age] = 0.69) from 7th…

Previous studies pointed out that dealing with difficult behaviour is perceived by teachers as a major challenge in inclusive settings. However, research on the students' perception of the classroom behavioural climate (CBC) is rare. Therefore, this study aims to examine students' perceptions of CBC and to identify predictors of CBC as well as…

How others behave (descriptive norm) and what they expect from us (injunctive norm) has a strong influence on how we behave. However, children and adolescents often overestimate the prevalence of negative behavior among their peers. The current study tested whether prompting peer norms for cyberbullying may foster anti-cyberbullying norms in an…

Immigrant boys show higher rates of antisocial behaviour. However, results of previous studies showed some contradictory findings in terms of intercultural differences in antisocial behaviour. In our study, we used an intercultural comparison of antisocial behaviour based on two different definitions of migration status (nationality vs. migration…

Student misbehavior is a pervasive problem and may seriously affect academic achievement. Previous research hints at different effects depending on whether achievement tests or achievement judgments are used as academic outcomes. Previous research also indicates that low achievement can conversely contribute to problem behavior and that low…
